Question details

l. The mass in grams of 1.00 mole the reaction: of o4.2H20 4. ven Ca 2H2 to exactly How many moles of H20 are needed react with 2.0 moles of Ca? A. 172 g B. 154 g C. 136 g D. 118 g A. 1.0 B. 2.0 C. 0.50 D. 4.0 2. Base your answer(s) to the following question (s) on the equation below, which represents an organic 5. Base your answer(s) to the following question(s) compound reacting with bromine. on the passage below. Acid rain is a problem in industrialized H -C-C-C-H countries around the world. Oxides of sulfur C C-C-H Bra and nitrogen are formed when various fuels are burned. These oxides dissolve in What is the gram-formula mass of the product in atmospheric water droplets that fall to earth as acid rain or acid snow. this reaction? While normal rain has a pH between 5.0 and 6.0 due to the presence of dissolved carbon dioxide, acid rain often has a pH of 4.0 or lower. This level of acidity can damage trees and plants, leach minerals from the soil, and cause the death of aquatic animals and plants. If the pH of the soil is too low, then quicklime, CaO, can be added to the soil to increase the pH. Quicklime produces calcium hydroxide when it dissolves in water. The molar mass of Ba (OH2 is Balance the neutralization equation below, using the smallest whole-number coefficients. B. 155.3 g A. 154.3 g HNO3 Ca(OH)2 D. 308.6 g Ca (NO H20
